Abstract

A power system (1) is provided. The power system (1) includes an AC-DC conversion module (11), a server board (12), a DC-DC converter (13), and a load (14). The AC-DC conversion module (11) is configured to convert an AC voltage (Vac1) to an intermediate DC voltage (Vdc1) which is greater than or equal to 100 V. The DC-DC converter (13) is disposed on the server board (12), electrically connected to the AC-DC conversion module (11) to receive the intermediate DC voltage (Vdc1), and configured to convert the intermediate DC voltage (Vdc1) to a load voltage (Vdc2). The DC-DC converter (13) includes submodules (131 to 13N) and a controller (130), input terminals of the submodules (131 to 13N) are electrically connected in series, output terminals of the submodules (131 to 13N) are electrically connected in parallel, and the controller (130) controls operation of the submodules (131 to 13N). The load (14) is disposed on the server board (12) and is electrically connected to the DC-DC converter (13) to receive the load voltage (Vdc2). The load (14) is configured to be powered by the load voltage (Vdc2).
